Description

[Detailed explanation of the idea] The present invention relates to a sliding door locking device.

In general, in a sliding door, a shoji door is placed inside a window frame consisting of a lower frame, an upper casing, and a vertical frame, and the shoji door is hung within the window frame so that it can be opened and closed freely along a rail section formed on the lower rim and the upper casing. It is constructed so that it can be hung and removed at a predetermined position.

For this reason, there is a danger that the shoji door may come off the window frame at a predetermined position, so in the past, after the shoji door was hung on the window frame, a movable or screw-fixed piece to prevent it from coming off was installed to open and close the shoji door. This prevents the shoji door from coming off the window frame when moving.

However, with the conventional structure, the shoji door can be opened and closed without providing a retaining piece, so it is very dangerous to forget to provide a retaining piece.

The present invention was developed in view of the above circumstances, and its purpose is to provide a sliding door locking device that can reliably prevent forgetting to operate the locking piece.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes an opening in a building (not shown), to which a window frame 2 is fixed by sealing or other means.

The window frame 2 includes an upper frame 2a, a lower frame 2b, and these upper and lower frames 2a.
